Higher Risk Of Neonatal Death Research Articles

Associations between the time interval from myomectomy to subsequent pregnancy and the obstetric outcomes: A population-based cohort study.

To investigate the associations between time interval from myomectomy to pregnancy (TIMP) and subsequent pregnancy and obstetric complications, and to explore whether these associations vary according to maternal age at birth. A retrospective population-based cohort study was conducted from 2008 to 2017. Data were extracted from the National Health Insurance Research Database and the Taiwan Maternal and Child Health Database, comprising 2024 379 births from 1 391 856 pregnancies. Eligible cases were identified using diagnostic and procedure codes; 4006 first singleton births in 4006 women after their first laparotomic myomectomy were identified. We estimated the risks of pregnancy and obstetric outcomes according to TIMP (<6, 6-11, and ≥12 months). Subgroup analysis was performed by further dividing according to maternal age at birth (18-34 vs ≥35 years old). We observed higher risks of gestational hypertensive disorders (adjusted odds ratio [aOR] 1.97, 95% confidence interval [CI] 1.22-3.18, P = 0.005) and neonatal death (aOR 4.59, 95% CI 1.49-14.18, P = 0.008) for TIMP of <6 months versus TIMP of 6-11 months. Likewise, a TIMP ≥12 months was associated with increased risks of gestational hypertensive disorders (aOR 1.72, 95% CI 1.14-2.58, P = 0.010), and neonatal death (aOR 3.27, 95% CI 1.16-9.24, P = 0.025) versus a TIMP of 6-11 months. In subgroup analysis, women over 35 years old still had higher risks of gestational hypertensive disorders when TIMP was <6 months (aOR 2.26, 95% CI 1.17-4.37, P = 0.015) or ≥12 months (aOR 2.04, 95% CI 1.17-3.54, P = 0.012), and a higher risk of neonatal death when TIMP was <6 months (aOR 4.05, 95% CI 1.06-15.53, P = 0.041); whereas women aged 18-34 years old did not. This study suggests that a TIMP between 6 and 11 months is associated with lower risks of gestational hypertensive disorders and neonatal death compared with a TIMP <6 months or ≥12 months, especially for women over 35 years old.

Abnormal Shape and Size of the Cardiac Ventricles Are Associated with a Higher Risk of Neonatal Death in Fetuses with Isolated Left Congenital Diaphragmatic Hernia

Introduction: The objective of this study was to evaluate the association between fetal cardiac deformation analysis (CDA) and cardiac function with severe adverse perinatal outcomes in fetuses with isolated left congenital diaphragmatic hernia (CDH). Methods: CDA in each ventricle (contractility, size, and shape), evaluated by speckle tracking and novel FetalHQ software, and markers of cardiac function (E/A ratios, pulmonary and aortic peak systolic velocities, and sigmoid annular valve diameters), were evaluated in fetuses with isolated left CDH. Two evaluations were performed: at referral (CDA and function) and within 3 weeks of delivery (CDA). Severe adverse neonatal outcomes were considered neonatal death (ND) or survival with CDH-associated pulmonary hypertension (CDH-PH). Differences and associations between CDA, cardiac function, and severe adverse outcomes were estimated. Results: Fifty fetuses were included, and seventeen (34%) had severe adverse neonatal outcomes (11 ND and 6 survivors with CDH-PH). At first evaluation, the prevalence of a small left ventricle was 34% (17/50) with a higher prevalence among neonates presenting severe adverse outcomes (58.8 [10/17] vs. 21.2% [7/33]; p = 0.01; OR, 5.03 [1.4–19.1; p = 0.01]) and among those presenting with neonatal mortality (8/11 [72.7] vs. 9/39 [23.0%]; p = 0.03; OR, 8.9 [1.9–40.7; p = 0.005]). No differences in cardiac function or strain were noted between fetuses with or without severe adverse outcomes. Within 3 weeks of delivery, the prevalence of small left ventricle was higher (19/34; 55.8%) with a more globular shape (reduced transverse/longitudinal ratio). A globular right ventricle was significantly associated with ND or survival with CDH-PH (OR, 14.2 [1.5–138.3]; p = 0.02). Conclusion: Fetuses with isolated CDH at risk of perinatal death or survival with CDH-PH had a higher prevalence of a small left ventricle and abnormal shape of the right ventricle.

Comparing the safety and effectiveness of various umbilical cord milking techniques and delayed cord clamping in full-term and preterm infants: A systematic review and meta-analysis.

We compare the hematocrit, hemoglobin, need for transfusion, recurrent phototherapy, serum bilirubin level, and serum ferritin at different time frames for the umbilical cord milking (UCM) and delayed cord clamping (DCC) in both full-term and preterm infants. A comprehensive search through various databases aimed to compare UCM and DCC studies until May 2nd, 2023. Cochrane and NIH tools assessed RCTs and cohorts, respectively. Meta-analysis employed Review Manager 5.4 software, calculating MD and RR with 95% CIs for continuous and dichotomous data. We included 20 studies with a total of 5189 infants. Regarding preterm infants, hematocrit level showed no significant difference between intact Umbilical Cord Milking (iUCM) compared to DCC (MD = -0.24, 95% CI [-1.11, 0.64]). Moreover, Neonatal death incidence was significantly higher with the UCM technique in comparison to DCC (RR = 1.28, 95% CI [1.01 to 1.62]). Regarding term and late preterm infants, Hematocrit level showed no significant difference between the iUCM or cUCM techniques compared to DCC (MD = 0.21, 95% CI [-1.28 to 1.69]), (MD = 0.96, 95% CI [-1.02 to 2.95]), respectively. UCM led to a higher risk of neonatal death in preterm infants compared to DCC. However, the incidence of polycythemia was lower in the UCM group. Additionally, UCM was associated with higher rates of severe IVH events. Based on these findings, DCC may be preferred due to its lower incidence of severe IVH and neonatal death.

Idiopathic polyhydramnios and pregnancy outcome: systematic review and meta-analysis.

To analyze outcomes of singleton pregnancies with idiopathic polyhydramnios through a systematic review and meta-analysis. Electronic databases, including MEDLINE, OVID, EBSCO, Cochrane collection and Science Citation Index, were searched from 1946 to 2019. Gray literature and tables of contents of relevant journals were also screened. Prospective and retrospective studies with a control group were included. Two authors independently reviewed the abstracts retrieved from the literature search. Inclusion criteria were: studies documented in English, singleton pregnancy and idiopathic polyhydramnios determined by amniotic fluid volume assessment on ultrasound. Exclusion criteria were: maternal diabetes, fetal structural or chromosomal anomaly, alloimmunization and intrauterine fetal infection. Twelve studies met the inclusion criteria, giving a total of 2392 patients with idiopathic polyhydramnios and 160 135 patients with normal amniotic fluid volume. Pregnancies complicated by idiopathic polyhydramnios were at a higher risk of neonatal death (odds ratio (OR), 8.68 (95% CI, 2.91-25.87)), intrauterine fetal demise (OR, 7.64 (95% CI, 2.50-23.38)), neonatal intensive care unit admission (OR, 1.94 (95% CI, 1.45-2.59)), 5-min Apgar score < 7 (OR, 2.21 (95% CI, 1.34-3.62)), macrosomia (OR, 2.93 (95% CI, 2.39-3.59)), malpresentation (OR, 2.73 (95% CI, 2.06-3.61)) and Cesarean delivery (OR, 2.31 (95% CI, 1.79-2.99)). This study suggests that pregnancies complicated by idiopathic polyhydramnios are at increased risk of adverse outcome. Future investigations should aim to determine an amniotic fluid volume threshold above which antenatal fetal surveillance is appropriate in the management of these pregnancies. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Obstetric and Perinatal Outcomes of Singleton Births Following Single- vs Double-Embryo Transfer in Sweden

Pregnancies resulting from assisted reproductive technology are associated with an increased risk of adverse perinatal outcomes compared with those following natural conception. Previous studies have shown an association of pregnancies resulting from transfer of multiple embryos with these negative findings. To determine the risk for adverse outcomes in singletons conceived through assisted reproduction using double-embryo transfer (DET) vs single-embryo transfer (SET). This cohort study used data from women who achieved singleton deliveries after SET or DET in Sweden between 2007 and 2017 as recorded in the National Quality Registry for Assisted Reproduction. All embryo transfers, at cleavage or blastocyst stage, replaced in fresh or frozen treatment cycles were included. Data on obstetric and neonatal outcomes were retrieved by linkage to the National Medical Birth Register. Naturally conceived singletons were included as a reference group. Data were analyzed between September 2021 and August 2022. Double-embryo transfer leading to singleton birth. Relative risk ratios or odds ratios (ORs) and absolute risk differences (ARDs) in percentage points with 95% CIs were calculated for obstetric and perinatal outcomes in singleton births conceived using DET vs SET. Among 1 115 863 singleton births, 30 713 singletons were born after SET and 5123 after DET. A higher risk of neonatal death was found in singletons after DET vs SET (OR, 2.67 [95% CI, 1.28-5.55]; ARD, 0.2 percentage points [95% CI, 0.0-0.4 percentage points]). In frozen embryo transfers, DET was associated with a higher risk of low birth weight (OR, 1.64 [95% CI, 1.19-2.25]; ARD, 2.0 percentage points [95% CI, 0.5-3.5 percentage points]). Among blastocyst transfers, DET was associated with very preterm birth (relative risk ratio, 2.64 [95% CI, 1.50-4.63]; ARD, 1.8 percentage points [95% CI, 0.3-3.4 percentage points]) and low birth weight (OR, 1.83 [95% CI, 1.29-2.60]; ARD, 3.2 percentage points [95% CI, 0.9-5.5 percentage points]). These results indicate a higher risk of adverse outcomes following DET, even when the result is a singleton birth, vs singletons born after SET. Adverse outcomes were mainly observed in singletons following DET using frozen embryos and blastocysts.

The Efficacy of Fetoscopic Laser Surgery in Twin-Twin Transfusion Syndrome: A Preliminary Vietnamese Study.

Twin-twin transfusion syndrome (TTTS) is a severe prenatal complication of monochorionic diamniotic twins (MCDA). If left untreated, TTTS is associated with a high risk of neonatal death and neurological complications. Various treatment methods for TTTS have been proposed, but fetoscopic laser surgery (FLS) is currently the primary treatment for TTTS in global fetal medicine centers. The objective of this study was to evaluate the outcome of TTTS following FLS treatment at Hanoi Obstetrics and Gynecology Hospital (HOGH), a new fetal medicine center in Vietnam. A prospective study of a series of 33 consecutive TTTS cases prior to 26 weeks of gestation subjected to FLS at HOGH in Vie-tnam between September 2019 to July 2021. Neonates were monitored for at least six months after birth. The survival rate of at least one fetus reached 84.85%. No short-term neurological complications have been reported upon follow-up of the newborn up to six months after birth. There were three stillbirth cases (9.09%), one case of preterm ruptured membra-nes (PROM) (3.03%) after seven days of surgery and three cases of recurrent TTTS after surgery using the Solomon technique (25%). No maternal complications were observed. The mean gestational age at birth was 33.76 ± 4.52 weeks, with a mean interval of 12.24 ± 6.67 weeks between intervention and delivery. Nine cases (30%) were born prematurely before 32 weeks. Additionally, 60% of recipients and nearly 90% of donors weighed less than 2500 grams. FLS leads to high survival rates for fetuses with TTTS. FLS seems to be an effective therapeutic option for TTTS before 26 weeks of gestation.

Survival analysis of neonatal mortality in Ghana using three population-based surveys

BackgroundNeonatal mortality in many low-and middle-income countries (LMICs) remains high despite global efforts at addressing this challenge. Tackling neonatal death in LMICs is further complicated by lack of reliable data from individual countries in the region to inform effective context specific interventions. This study investigates the probability of neonatal survival and socio-demographic risk factors of neonatal mortality in Ghana.MethodsPooled data from three population-based surveys (N = 12,148) were analysed using multivariable Cox Proportional Hazards regression models.ResultsThe risk of dying within the first 28 days of life was highest in the first week of life (early neonatal period), it then decreases sharply around the middle of the second week of life and remains low over the late neonatal period. Adjusted hazard ratios (HRs) showed that: rural residency (HR = 1.80, 95% CI: 1.15-2.75); birth order 2-3 (HR = 1.63, 95% CI: 1.10-2.42); birth order ≥7 (HR = 1.89, 95% CI: 1.07-3.33) increased the risk of neonatal death. Additionally, children born to women who were obese had higher risk of neonatal death (HR = 1.69, CI: 1.12-2.56) compared with those of women with optimal weight. Disparities in the risk of neonatal death by geographical regions were also found.ConclusionThe risk of neonatal mortality is highest during the first week of life and it is socio-demographically patterned. The findings emphasise the need to tackle socio-demographic risk factors of neonatal mortality in order to achieve the Sustainable Development Goal 3, which is aimed at reducing neonatal mortality to 12 per 1000 live births by the year 2030.

Geospatial analysis of determinants of neonatal mortality in Ghana

BackgroundGhana did not meet the Millennium Development Goal 4 of reducing child mortality by two-thirds and may not meet SDG (2030). There is a need to direct scarce resources to mitigate the impact of the most important risk factors influencing high neonatal deaths. This study applied both spatial and non-spatial regression models to explore the differential impact of environmental, maternal, and child associated risk factors on neonatal deaths in Ghana.MethodsThe study relied on data from the Ghana Demographic and Health Surveys (GDHS) and the Ghana Maternal Health Survey (GMHS) conducted between 1998 and 2017 among 49,908 women of reproductive age and 31,367 children under five (GDHS-1998 = 3298, GDHS-2003 = 3844, GDHS-2008 = 2992, GDHS-2014 = 5884, GMHS-2017 = 15,349). Spatial Autoregressive Models that account for spatial autocorrelation in the data at the cluster-level and non-spatial statistical models with appropriate sampling weight adjustment were used to study factors associated with neonatal deaths, and a p-value less than 0.05 was considered statistically significant.ResultsPopulation density, multiple births, smaller household sizes, high parity, and low birth weight significantly increased the risk of neonatal deaths over the years. Among mothers who had multiple births, the risk of having neonatal deaths was approximately four times as high as the risk of neonatal deaths among mothers who had only single birth [aRR = 3.42, 95% CI: 1.63–7.17, p < 0.05]. Neonates who were perceived by their mothers to be small were at a higher risk of neonatal death compared to very large neonates [aRR = 2.08, 95% CI: 1.19–3.63, p < 0.05]. A unit increase in the number of children born to a woman of reproductive age was associated with a 49% increased risk in neonatal deaths [aRR = 1.49, 95% CI: 1.30–1.69, p < 0.05].ConclusionNeonatal mortality in Ghana remains relatively high, and the factors that predisposed children to neonatal death were birth size that were perceived to be small, low birth weight, higher parity, and multiple births. Improving pregnant women’s nutritional patterns and providing special support to women who have multiple deliveries will reduce neonatal mortality in Ghana.

Impact of maternal mental health problems on perinatal outcomes for the infant

Abstract Background Mounting evidence suggests that mental health problems in pregnant women may negatively affect the intra- and extrauterine health and development of the child. This is especially of concern as the prevalence of mental health problems in pregnant women is high and believed to be increasing. We set out to quantify the effect of maternal mental health status on the risk of adverse perinatal outcomes for the infant. Methods We undertook a nationwide register-based cohort study including children born alive in Denmark between 2000 and 2016. The exposed cohort was children born to mothers with mental health problems in the two years prior to childbirth that had been cared for in primary care settings only (Group 1, minor problems, n = 71 759) or had required psychiatric intervention (Group 2, moderate-severe problems, n = 41 099). All non-exposed children served as comparison group (n = 908 268). We calculated risk ratios (RRs) with 95% confidence intervals (CI) for each perinatal outcome of interest. Results Infants in Group 1 as well as Group 2 were at higher risk of neonatal death than infants born to unaffected mothers, although for Group 2 the trend was non-significant (Group 1: adjusted RR (aRR) 1.34, 95% CI 1.17-1.52; Group 2: aRR 1.11, 95% CI 0.94-1.32). Both exposure groups were furthermore at significantly increased risk of 5-minute Apgar scores &amp;lt;7 (Group 1: aRR 1.27, 95% CI 1.17-1.37; Group 2: aRR 1.52, 95% CI 0.94-1.32) and &amp;lt;4 (Group 1: aRR 1.26, 95% CI 1.10-1.44; Group 2: aRR 1.28, 95% CI 1.08-1.52) and of hospital admission in the neonatal period (Group 1: aRR 1.22, 95% CI 1.19-1.24; Group 2: 1.29, 95% CI 1.26-1.32), paralleled by a significantly higher risk of preterm birth and several neonatal morbidities. Conclusions Infants born to mothers with moderate-severe as well as minor mental health problems were at increased risk of multiple adverse perinatal outcomes, thus calling for effective preventive strategies to improve outcomes in both groups.

Oxygen systems to improve clinical care and outcomes for children and neonates: A stepped-wedge cluster-randomised trial in Nigeria.

Improving oxygen systems may improve clinical outcomes for hospitalised children with acute lower respiratory infection (ALRI). This paper reports the effects of an improved oxygen system on mortality and clinical practices in 12 general, paediatric, and maternity hospitals in southwest Nigeria. We conducted an unblinded stepped-wedge cluster-randomised trial comparing three study periods: baseline (usual care), pulse oximetry introduction, and stepped introduction of a multifaceted oxygen system. We collected data from clinical records of all admitted neonates (<28 days old) and children (28 days to 14 years old). Primary analysis compared the full oxygen system period to the pulse oximetry period and evaluated odds of death for children, children with ALRI, neonates, and preterm neonates using mixed-effects logistic regression. Secondary analyses included the baseline period (enabling evaluation of pulse oximetry introduction) and evaluated mortality and practice outcomes on additional subgroups. Three hospitals received the oxygen system intervention at 4-month intervals. Primary analysis included 7,716 neonates and 17,143 children admitted during the 2-year stepped crossover period (November 2015 to October 2017). Compared to the pulse oximetry period, the full oxygen system had no association with death for children (adjusted odds ratio [aOR] 1.06; 95% confidence interval [CI] 0.77-1.46; p = 0.721) or children with ALRI (aOR 1.09; 95% CI 0.50-2.41; p = 0.824) and was associated with an increased risk of death for neonates overall (aOR 1.45; 95% CI 1.04-2.00; p = 0.026) but not preterm/low-birth-weight neonates (aOR 1.30; 95% CI 0.76-2.23; p = 0.366). Secondary analyses suggested that the introduction of pulse oximetry improved oxygen practices prior to implementation of the full oxygen system and was associated with lower odds of death for children with ALRI (aOR 0.33; 95% CI 0.12-0.92; p = 0.035) but not for children, preterm neonates, or neonates overall (aOR 0.97, 95% CI 0.60-1.58, p = 0.913; aOR 1.12, 95% CI 0.56-2.26, p = 0.762; aOR 0.90, 95% CI 0.57-1.43, p = 0.651). Limitations of our study are a lower-than-anticipated power to detect change in mortality outcomes (low event rates, low participant numbers, high intracluster correlation) and major contextual changes related to the 2016-2017 Nigerian economic recession that influenced care-seeking and hospital function during the study period, potentially confounding mortality outcomes. We observed no mortality benefit for children and a possible higher risk of neonatal death following the introduction of a multifaceted oxygen system compared to introducing pulse oximetry alone. Where some oxygen is available, pulse oximetry may improve oxygen usage and clinical outcomes for children with ALRI. Australian New Zealand Clinical Trials Registry: ACTRN12617000341325.

The effect of an mhealth clinical decision-making support system on neonatal mortality in Ghana

Abstract Background Mhealth interventions promise to bridge gaps in clinical care but documentation of their effectiveness is limited. We evaluated the utilization and effect of an mhealth clinical decision-making support intervention that aimed to improve neonatal mortality in Ghana by providing access to emergency neonatal protocols for frontline health workers. Methods In the Eastern Region of Ghana, sixteen districts were randomized into two study arms (8 intervention and 8 control clusters) in a cluster-randomized controlled trial. Institutional neonatal mortality data were extracted from the District Health Information System-2 during an 18-month intervention period. We performed an intention-to-treat analysis and estimated the effect of the intervention on institutional neonatal mortality (primary outcome measure) using grouped binomial logistic regression with a random intercept per cluster. This trial is registered at ClinicalTrials.gov (NCT02468310). Results There were 65,831 institutional deliveries and 348 institutional neonatal deaths during the study period. Overall, 47·3% of deliveries and 56·9% of neonatal deaths occurred in the intervention arm. During the intervention period, neonatal deaths increased from 4·5 to 6·4 deaths and, from 3·9 to 4·3 deaths per 1,000 deliveries in the intervention arm and control arm respectively. The odds of neonatal death was non-significantly higher in the intervention arm compared to the control arm (odds ratio 2·10; 95% CI (0·77;5·77); p = 0·15). The correlation between the number of protocol requests and the number of deliveries per intervention cluster was 0·71 (p = 0·05). Conclusions Non-significant higher risk of neonatal death observed in intervention clusters may be due to problems with birth and death registration, unmeasured and unadjusted confounding, and unintended use of the intervention. The findings underpin the need for careful and rigorous evaluation of mhealth intervention implementation and effects. Key messages Supposedly effective interventions must be evaluated in context before they are scaled-up. Mechanisms influencing outcomes in context must be considered in the design and evaluation of interventions.

Birth weight as a risk factor for neonatal mortality: Breed-specific approach to identify at-risk puppies

In numerous species, low birth weight is a risk factor for neonatal mortality. In the canine species, definition of a low birth weight is complex due to the huge interbreed variability in size. To identify puppies at higher risk of neonatal death, data from 6,694 puppies were analysed. The data were collected from 75 French breeding kennels, examining 27 breeds and totaling 1,202 litters of puppies. Generalised linear mixed models allowed to identify birth weight, birth weight heterogeneity within the litter, and size of the breeding kennel as significant risk factors for neonatal mortality. Receiver Operating Characteristics (ROC) and classification and regression tree (CART) analyses were combined to define breed specific thresholds for birth weight allowing the identification of puppies at higher risk of neonatal mortality. Due to differences in birth weights between breeds, including when belonging to the same breed size, analyses were conducted at the breed level. First, ROC analysis thresholds were successfully established for 12 breeds (area under the ROC ≥ 0.70; sensitivity ≥ 75%; specificity: 45–68%) and they ranged from 162 g in the Maltese to 480 g in the Bernese Mountain dog. Secondly, CART analysis thresholds from 22 breeds ranged from 105 g in the Maltese and 436 g in the Boxer. Puppies were grouped into three categories according to birth weight: low, moderate and high risk of neonatal mortality (higher than the ROC threshold, between ROC and CART thresholds, and lower than the CART threshold respectively). In the current study, 44% of the puppies were classified as at moderate risk and 5.3% for a high risk of neonatal mortality. Thresholds defined by CART analysis (and not ROC analysis) were used to define low birth weight puppies and were sometimes quite different between breeds with similar birth weight distributions suggesting a variable relationship between birth weight reduction and neonatal death. These results allow the identification of puppies at an increased risk of neonatal death, thus requiring specific nursing to improve their chances of survival. With these high risk puppies identified, both animal welfare and kennel productivity is predicted to improve.

Twin births in Jordan: incidence, trends, risk factors and implications for under-five mortality: evidence from the 2012 Jordan Population and Family Health Survey.

Research on twinning in developed countries is well documented, but little is known about twinning in less-developed countries due to a lack of data or data limitations. This study examined the level of, trends in and determinants of twin births and their survival under age five in Jordan, using the 2012 Jordan Population and Family Health Survey (JPFHS) data. The birth history of 11,352 women included in the JPFHS provided information on 9859 live births that occurred within five years of the survey date, and these constituted the study subjects. Descriptive statistics, and bivariate and multivariate multilevel logistic regression models were used for data analysis. About 3.5% of the total live births were twins, which is one of the highest rates in developing countries. The twinning rate showed an increasing trend in Jordan, increasing by 45% from 2.4% in 1990 to 3.5% in 2012. Higher maternal age at child birth, higher parity, poor and richer economic status, contraceptive use status, secondary and above level of education of mothers and non-consanguinity were found to be associated with a higher rate of twin births in Jordan. Twins were observed to have a higher risk of low birth weight, being smaller in physical size at birth and at more than four times higher risk of neonatal death compared with singletons. To reduce the risk adverse outcomes of twin pregnancies and further improve maternal and child health, antenatal, delivery and postnatal care should be tailored towards the special needs of twin pregnancies and twin births in Jordan Twin pregnancies should be detected at the early stage of pregnancy so that perinatal outcomes can be improved by frequent prenatal visits, health education, counselling and proper management of peripartum complications.

Trial of labor versus elective repeat cesarean delivery in twin pregnancies after a previous cesarean delivery—A systematic review and meta‐analysis

To perform a systematic review of success rates of trial of labor after cesarean (TOLAC) and maternal and neonatal outcomes in twin pregnancy versuselective repeat cesarean delivery (ERCD). We searched MEDLINE, EMBASE, and Web of Science from data inception to May 2018 with no language or regional restrictions, to identify all studies that compared twin TOLAC and ERCD for maternal and/or neonatal outcomes. The Newcastle-Ottawa Scale was used to assess the methodological quality of the included studies. We assessed the pooled relative risk and mean difference using a random-effects model. The pooled event rates for successful VBAC, cesarean deliveryfor twin B after vaginal delivery of twin A, and uterine rupture were determined. Of the 841 citations identified, 10 were eligible for analysis (2336 TOLAC cases and 5763 ERCD cases). The pooled event rates for successful VBAC and uterine rupture during TOLAC were 72.2% (95% CI 59.7%-83.2%) and 0.87% (95% CI 0.51%-1.31%), respectively. TOLAC was associated with a significantly higher risk of neonatal death (RR 3.02 [95% CI 1.07-8.54])with no significant differences in mean gestational age at birth, NICU admission rates, or 5-minute Apgar <7. Although the risk for maternal infectious morbidity was significantly lower with TOLAC(RR 0.48 [95% CI 0.25-0.90]), risks of uterine dehiscence, blood transfusions, and hysterectomy were comparable. Twin TOLAC is associated with a relatively high rate of successful vaginal delivery and a low risk of uterine rupture. The finding of higher neonatalmortality rates may be influenced by prematurity, but requires further investigation.

375: Trial of labor versus elective repeat caesarean section in twin pregnancies after a previous caesarean

A growing number of women with multiple gestations and a previous cesarean section (CS) are candidates for a trial of labor after cesarean (TOLAC). Evidence to guide decisions regarding optimal mode of delivery in this population is lacking. Our objective was to perform a systematic review and meta-analysis of success rates and maternal and neonatal outcomes in women with twin pregnancy attempting TOLAC versus elective repeat cesarean section (ERCS). We searched MEDLINE, Embase, and Web of Science from data inception to May 2018 with no language or regional restrictions, to identify all studies that compared TOLAC and ERCS in twin gestations for maternal and/or neonatal outcomes. Our primary outcome was adverse maternal and neonatal outcomes in either delivery mode. Newcastle-Ottawa Scale was used to assess the methodological quality of the included studies. We assessed the pooled relative risk and mean difference using a random-effects model of maternal and neonatal outcomes by comparing twin pregnancies with a previous CS that underwent TOLAC to ERCS. The pooled event rate for successful VBAC and uterine rupture in women who underwent TOLAC was determined using a random-effects model. Of the 841 citations identified, 10 were eligible for analysis (8,099 pregnancies, with 2,336 TOLAC cases and 5,763 ERCS cases, reporting the outcome of 3,188 neonates). The pooled event rate for a successful VBAC was 72.2% (95% CI 59.7-83.2%). The pooled event rate for uterine rupture during TOLAC was 0.87% (95% CI 0.51%-1.31%). TOLAC was associated with a significantly higher risk of neonatal death (RR 3.02: 95% CI, 1.07-8.54) compared to ERCS, with no significant differences in mean gestational age at delivery, NICU admission rates or 5’ Apgar<7 between the groups. While infection rate was significantly lower in women undergoing TOLAC (RR 0.48: 95% CI, 0.25-0.90) the rate of, uterine rupture, hysterectomy and dehiscence was comparable. TOLAC in twins is associated with successful vaginal delivery of both twins in a majority of the cases with rupture rates of less than 1%. While maternal infectious morbidity decreases in TOLAC, the finding of increased rate of neonatal death raises concerns and requires further investigation.View Large Image Figure ViewerDownload Hi-res image Download (PPT)

HUBUNGAN KELAHIRAN KEMBAR DENGAN KEMATIAN NEONATAL DI INDONESIA: ANALISIS DATA SDKI 2012

Background: Neonatal Mortality Rate (NMR) is one indicator of the Sustainable Development Goals (SDGs) and contributes to the infant mortality rate. Twin birth is one of the risk factors for neonatal death, 6 times compared to single birth. The possibility of an increase in twin birth rates, and the high risk posed, could contribute negatively to efforts to reduce neonatal deaths in Indonesia.Objective: This study aims to determine the proportion of twin births, also analyzing association of twin birth with neonatal mortalityMethod: This study used the 2012 Indonesian Health Demographic Survey (IDHS), a cross-sectional designs that covers all provinces. The population was all children born alive in 2007-2012 from women of childbearing age who met the inclusion and exclusion criteria. The study sample was 15,083 live births. Result: The twin births rate in Indonesia by 14 per 1,000 births, increased from previous study 7,2 per 1.000 births in 1997-2007. There was significant association between twin births with neonatal mortality (POR 2,39; 95% CI 1,43-4,01; p-value 0,00), after controlled parity and birth weight. Conclusion: The proportion of twin births in Indonesia has increased almost doubled. Twins is high risk of neonatal death because they are born with low birth weight.

S100-alarmin-induced innate immune programming protects newborn infants from sepsis

The high risk of neonatal death from sepsis is thought to result from impaired responses by innate immune cells; however, the clinical observation of hyperinflammatory courses of neonatal sepsis contradicts this concept. Using transcriptomic, epigenetic and immunological approaches, we demonstrated that high amounts of the perinatal alarmins S100A8 and S100A9 specifically altered MyD88-dependent proinflammatory gene programs. S100 programming prevented hyperinflammatory responses without impairing pathogen defense. TRIF-adaptor-dependent regulatory genes remained unaffected by perinatal S100 programming and responded strongly to lipopolysaccharide, but were barely expressed. Steady-state expression of TRIF-dependent genes increased only gradually during the first year of life in human neonates, shifting immune regulation toward the adult phenotype. Disruption of this critical sequence of transient alarmin programming and subsequent reprogramming of regulatory pathways increased the risk of hyperinflammation and sepsis. Collectively these data suggest that neonates are characterized by a selective, transient microbial unresponsiveness that prevents harmful hyperinflammation in the delicate neonate while allowing for sufficient immunological protection.

Risk factors associated with neonatal deaths: a matched case–control study in Indonesia

BackgroundSimilar to global trends, neonatal mortality has fallen only slightly in Indonesia over the period 1990–2010, with a high proportion of deaths in the first week of life.ObjectiveThis study aimed to identify risk factors associated with neonatal deaths of low and normal birthweight infants that were amenable to health service intervention at a community level in a relatively poor province of Indonesia.DesignA matched case–control study of neonatal deaths reported from selected community health centres (puskesmas) was conducted over 10 months in 2013. Cases were singleton births, born by vaginal delivery, at home or in a health facility, matched with two controls satisfying the same criteria. Potential variables related to maternal and neonatal risk factors were collected from puskesmas medical records and through home visit interviews. A conditional logistic regression was performed to calculate odds ratios using the clogit procedure in Stata 11.ResultsCombining all significant variables related to maternal, neonatal, and delivery factors into a single multivariate model, six factors were found to be significantly associated with a higher risk of neonatal death. The factors identified were as follows: neonatal complications during birth; mother noting a health problem during the first 28 days; maternal lack of knowledge of danger signs for neonates; low Apgar score; delivery at home; and history of complications during pregnancy. Three risk factors (neonatal complication at delivery; neonatal health problem noted by mother; and low Apgar score) were significantly associated with early neonatal death at age 0–7 days. For normal birthweight neonates, three factors (complications during delivery; lack of early initiation of breastfeeding; and lack of maternal knowledge of neonatal danger signs) were found to be associated with a higher risk of neonatal death.ConclusionThe study identified a number of factors amenable to health service intervention associated with neonatal deaths in normal and low birthweight infants. These factors include maternal knowledge of danger signs, response to health problems noted by parents in the first month, early initiation of breastfeeding, and delivery at home. Addressing these factors could reduce neonatal deaths in low resource settings.

Why are babies born before arrival at health facilities in King Sabata Dalindyebo Local Municipality, Eastern Cape, South Africa? A qualitative study.

IntroductionBabies born before arrival at a health facility have a higher risk of neonatal death and their mothers a higher risk of maternal death compared with those born in-facility. The study explored the reasons for mothers giving birth before arrival (BBA) at health facilities and their experiences of BBA.MethodsA qualitative research design was used. Individual and focus group interviews of BBA mothers and of nurses were undertaken at a community health centre and a district hospital in King Sabata Dalindyebo Local Municipality.ResultsReasons for BBA included a lack of transport, a lack of security at night that deterred mothers from travelling, precipitate labour, failure to identify true labour, and a lack of waiting areas at health facilities. Traditional and cultural beliefs favouring childbirth at home and nurses’ negative attitudes during antenatal care and labour influenced mothers to go to health facilities when in advanced labour. Mothers were aware of possible complications associated with BBA.ConclusionSocio-economic, individual, cultural and health system factors influence the occurrence of BBA. Relevant parties need to address these factors to ensure that all babies in the King Sabata Dalindyebo Local Municipality are delivered within designated health facilities.

Perinatal outcomes after hypertensive disorders in pregnancy in a low resource setting.

The objective of this study was to evaluate perinatal outcomes of pregnancies complicated by hypertensive disorders in pregnancy in an urban sub-Saharan African setting. A prospective cohort study of 1010 women of less than 17 weeks of gestation was conducted at two antenatal clinics in Accra, Ghana, between July 2012 and March 2014. Information about hypertensive disorders was available for analysis on 789 pregnancies. The main outcomes were pre-term birth, birthweight, Apgar scores, small for gestational age and mortality. Relative risk (RR, 95% confidence interval (CI)) for the association between hypertensive disorders of pregnancy and perinatal outcomes was assessed using logistic regression adjusting for potential confounders. A total of 88.7% of women remained normotensive, 7.5% developed pregnancy-induced hypertension, 2.0% had chronic hypertension, and 1.7% developed (pre-)eclampsia. No adverse effects were observed in women with pregnancy-induced hypertension. Women with chronic hypertension were more likely to have a lower gestational age at delivery (38.0 ± 2.3 weeks vs. 39.0 ± 1.9 weeks, P = 0.04) and higher risk of pre-term delivery (aRR 4.63, 95% CI 1.35-15.91). Women with pre-eclampsia had emergency Caesarean section significantly more often (88.9% vs. 50%, P = 0.04), with a higher risk for low birthweight infants (aRR 7.95, 95% CI 1.41-44.80) and a higher risk of neonatal death (aRR 18.41, 95% CI 1.20-283.22). Comparable to high-income countries, in Accra hypertensive disorders during pregnancy were associated with increased risk of adverse perinatal outcomes necessitating maternal and newborn care.
